20090088807 | Locking Screw System With Relatively Hard Spiked Polyaxial Bushing - A polyaxial locking screw system includes a bone plate defining a plate hole with an inner spherical surface and a relatively harder split polyaxial bushing with a outer spherical surface provided within the plate hole for receiving a bone screw. In one embodiment, the plate is formed from titanium alloy, while the bushing is formed from a cobalt chrome alloy. The outer surface of the polyaxial bushing includes a plurality of spikes. When the screw is inserted into the bushing, since the bushing material is considerably harder than the plate material, the forceful expansion of the bushing during screw insertion causes the spikes to penetrate into the inner spherical surface of the hole, thereby increasing the frictional engagement of the bushing to the plate to lock the screw at a desired angle. | 04-02-2009 |

The at least one plate is adapted to be customized to the shape of a patient's bone. The system also includes a plurality of fasteners including at least one locking fastener for attaching the bone plate to the bone. At least one of the holes is a threaded hole. Guides for plate benders, drills, and/or K-wires can be pre-assembled to the threaded holes, and the locking fastener can lock into any of the threaded holes after the guides are removed. | 05-14-2009 |
20100069969 | Low Profile Screw and Washer System for Bone Plating - A low profile bone screw system includes a retainable washer and a low profile bone screw having a smooth conical head for insertion into the washer. The washer has an axial bore with a conical portion for fully seating the screw head and a smooth outer surface shaped like the head of a conventional compression bone screw head. Washer dispensing units are also provided. | 03-18-2010 |
20100137868 | Method of implanting a modular fracture fixation system - A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one diaphyseal plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one diaphyseal plate. The system preferably includes several end plates and diaphyseal plates to accommodate anatomy of various sizes. | 06-03-2010 |
20110264100 | Bone Plate Bender System - A pair of plate benders are provided for bending a bone plate. Each bender includes a lever arm having a first end and a second end. The first end includes a fulcrum for placement on the upper surface of the plate, and a foot insertable through the oblong screw hole to contact the lower surface of the plate. The second end includes a cut-out with a central divider. The cut-out has a length dimensioned to extend widthwise about the plate at the location of the oblong screw hole with the divider extending into the oblong screw hole for stability. The second end may also be provided with a deep slot that accommodates the thickness of the plate. In use, plate benders with such structure can be used in pairs to longitudinal bend the plate; bend the plate in plane; or twist the plate along its axis. | 10-27-2011 |
20120323281 | Method of Implanting a Modular Fracture Fixation System - A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one diaphyseal plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one diaphyseal plate. The system preferably includes several end plates and diaphyseal plates to accommodate anatomy of various sizes. A method for coupling the plates to the bone is also provided. | 12-20-2012 |
20130150899 | Bone Plate with Two Different Sizes of Discrete Drill Guides Connected to the Plate - A system for the internal fixation of a fractured bone includes a bone plate with threaded holes and two types of guides threadedly connected within the threaded holes. One guide is taller and smaller in diameter, whereas the other guide is shorter and wider in diameter. The guides provide guidance for drilling a hole through the guide and screw hole, and optional bending of the plate at the guide. The guides have structure allowing the guides to be individually removed through rotation. | 06-13-2013 |
20140061231 | Screw and Washer Dispenser System - A low profile bone screw system includes a retainable washer and a low profile bone screw having a smooth conical head for insertion into the washer.
